Develop Bugs

I need researchers

APQ8064 1.5 - 1.7 GHz Quad Krait Adreno 320 QXGA 1080p No Modem 20 MP
gpsOneGen 8A with
GLONASS
Hexagon QDSP6

(480Mbps)
802.11a/b/g/n*
BT 3.x + HS
BT 4.0/LE FM Rx/Tx*
28nm
that is our soc.
what i need are the following answers.
---How many gpus do we have so i can set the number of gpus in the kernel? The current value is limited at 16.
---Specs on the display. (factory specs)
---Does the s4 support multi-core scheduler's? (awesome if it did)
---Also I need someone to find the various address lines in menuconfig for all variants including the n4. We might be able to make a universal kernel using that information.
---Are we using the first or second dsp6 version.
These questions directly effect the kernel

What addresses do you want? We all including mako use the same kernel address, Ramdisk varies, modem I don't remember on the top of my head. I have sbl3 and lk at home. But I don't think you care about those (for the kernel).

When you say how many gpus do we have do you mean how many cores does the gpu have

So it is a quad core GPU then.

That more seems like its a quad core soc's GPU. 4 cores doesn't seem right

Yea, especially with a 64 core gpu showing up at CES for the tegra 4.
I bet it is 16, maybe more.

Well 16 seems low, it could be 16 but it would be nice if it was more and the kernel is holding back. That does happen

Well, my pals iPhone 5 smoked this phone in the gpu. I read an article that the new tegra is 64 core and it was a big deal. The tegra 3 was 12 from what I have found but a lot are only 4. I guess it is more the motion in the ocean than the size.
If I find out more I will let you know.
I found this too. http://www.reviewresults.in/reviewresults/post/2012/09/29/Tegra-3-vs-Adreno-320.aspx
It shows the Tegra 3 with 12 which I know is correct.

It's funny how everyone puts these phones against the iphone and I pad without realizing how much of a beast this gpu is. Apple has been forced to use 3 sgs543 gpus each with 4 sub cores on the iphone 5 to get the performance that this one gpu gets with four sub cores. Just like when nvidia says their gpu has 64 cores it's 64 sub cores on one gpu.

Part of the reason that iproducts benchmark so well is due to less products to support and common socs throughout. That way, they can easily optimize the os for each product.

That's what everyone said about a quad core. Yet here we are.
Sent from my SGH-T889 using Tapatalk 2

big.LITTLE does not activate all eight cores at the same time towards a task.
You will either get quad-core Cortex-A15 performance (heavy loads) or quad-core Cortex-A7 performance (light loads).
Gaming system emulation is limited by the CPU, not the GPU. The Exynos 5 will be a step up but probably not enough.

Wont effect battery life as long as propper governors are set and the batter is atleast 2700 (I now thats smaller than ours but so will the entire sg4 compared to the gn2)... inter-processor fluidity, gui, screen size, android version, etc should better battery life as well

Like I said. You do understand that these telephones pack enough processing power if not more than the original PS had. Probably. I haven't actually checked but I'm pretty sure Thad note 3 will handle emulating ten year old games....
The question that should be being asked is if someone can develop an emulator that isn't buggy as hell
Sent from my Nexus 7 using Tapatalk 2

The entire purpose of the octa core is to improve battery. When the device doesn't need to run at high power the second 4 cores a low power arm 7 will take over. The are saying it will improve battery by 70%. I will have to see that to believe it but if they say 70% I bet we can count on gaining at least 40% which would be awesome.

I just can't wait for KLP. I was reading they are going to optimize it for quad core cpu's and will also do allot of battery optimization. This phone here, the Note 2 is a beast of a phone as it is. The battery life is great, the screen is amazing and I've been using the s-pen more and more and I like it much more then I thought I would.
Yeah the S4 will be nice but the Note 3, that will be amazing. Kinda like the s3 then the Note 2 comes out with better everything and a much better screen. I can't handle pen tile screens.

CPU performance

It may be a noob question, but why does our device OC'd higher than other devices not outperform newer phones like the s4 or HTC One? Are there other factors that weigh in or is it Sammy doing something we can't undo?
Sent from my GT-N7105 using XDA Premium HD app

Different CPU architectures, and other parts so you cannot compare mhz vs mhz. Also depends on what you are testing exactly.

Outperformed by what comparison ???
Too many variables exist to compare anything. ..and benchmark scores do not count. ..
The best device is the one users enjoy the most. ...not the one that boasts about being "better" than it's rival competition. ..That is a marketing campaign. ..
The note 2 is not designed to be the main stream power phone. ..it is a unique niche device with nothing less than impressive specifications. ....and regardless of what the competition says, will run exceptionally well against any devices on the market who share the same production time frame, and similar hardware/software......g

I know I'm going to get some heat for this, but quadrant scores are around 12750 whereas my note 2 has topped at around 8500...I'm not saying I can't do anything less on our device; I do enjoy having the highest performance of anything out there
Sent from my GT-N7105 using XDA Premium HD app

Your problem is that you're equating quadrant score with sheer performance. It's no like a dynometer that gives a accurate reading. Ie - if you took a brand new sports car and put it on a dyno it would spit out nearly identical hp and torque numbers test after test, but if you ran quadrant test after test you would get varying scores. I've had score differences of up to 400 points when I ran the test back to back. The same with antutu.

Haha, like I said, I knew I'd get get heat for that, and I realize benchmarks aren't the most accurate way of determining power and performance...but I do like the bragging rights of saying that mine is numerically higher. I know it's kind of wrong, but it's also fun to mess with the settings and find what combos get the best results which led me to this post. I was also more curious as to why even though our device clocked higher with otherwise similar specs still don't match up.

You're asking the same question that I just answered. It doesn't matter the number of cores or the mH it's clocked at. There are too many variables to figure it out. Think about the different frameworks, the numerous system processes running, the apps installed, system apps, settings, tweaks... If you had identical devices running all the same stuff you would still get varying results.

Its not so much the cpu that is the biggest change in quadrant its in the power of the gpu that the note 2 has a mali 400 while some models of the S4 have much more powerful gpu's

Does that even matter in Quadrant? If you have a device with vsync off then it will score much higher in GPU than the Note 2 with Vsync.
Also, if you are going to only focus on Benchmarks to compare, at least use a more decent test or various tests to get a broader perspective like 3DMark, Antutu and Vellamo.

S4 Pro or Snapdragon 600?

So I'm currently very confused. I downloaded the app called CPU-Z to check out the internals of the G Pro and right up top it said that the chipset is the Snapdragon S4 Pro (keep in mind I'm using the AT&T model). I thought this must be an error of the app, seeing as I knew that the G Pro is supposed to have a Snapdragon 600 chip. I then went to both Antutu and Quadrant, and both stated that the phone has a Qualcomm QTC APQ8064 MTP processor, which I looked up and found is the S4 Pro from last year. I've always wondered why my G Pro tends to lag a bit and why benchmarks aren't as high as the One or the S4. Did I get fooled into thinking this device ran the Snapdragon 600?

Apparently no one knows. I've tried researching but couldn't find anything so I came to this forum. To me, it makes sense that the phone runs last year's S4 Pro like all the benchmarks say, due to the fact that the phone is quite laggy in daily use and scores very low compared to the Galaxy S4 and HTC One in benchmarks, both of which definitely have Snapdragon 600 processors.

24k Antutu low?
Maybe still cpu z bug, check comment at Playstore
Many people have no accurate CPU
Ex: One V = Snapdragon S1, it should be Snap S2
Nexus 4 S600, it should be S4 pro
And post your antutu after disable thermal throttling

Cpu z reports incorrect processor on many models. Att site specs clearly state it has the snapdragon 600 8064t. The clock is at 1.7 which matches the recommended clock for the sd 600. I would not be so quick to think LG would lie about the phones components.

Lol, I never said 24k was low. I mentioned that the G Pro was consistently not meeting anything close to that, as it scored more in the 17k range consistently, which is more indicative of the Snapdragon S4.

No, it just indicates that throttling caps the frequency more aggressively than on HTC1 or SGS4 so to G Pro not to get as hot as them. The same was with Nexus4, it throttled sooner than, say, ASUS Padfone2 and got lower scores in all benchmarks

I have seen YouTube review about real racing 3 which runs smoothly on that Galaxy note 4 however this game is laggy on my Verizon note 4, don't if this is common or snapdragon slower than Samsung Exynox? I am sure the power saving is set to off

BTW, I just tested the game with power saving mode--restrict performance turned on, and the performance was similar to power saving mode off. So could it be a bug that the restrict performance is set to on by default?

how many FPS ? there are no problem with other games ?

AT&T note 4 here game runs awful compared to my note pro it's slow and choppy and acts like it's running on an outdated processor.

install GameBench you will see the CPU and GPU is not overload, so i guess, it's the game that is not optimized or compatible with the 805 processor

Just found a review on www.frandroid.com, it is in France but basically it says the CPU and GPU performance is not stable, While the CPU speed was lowered from 2.7Ghz to 1Ghz after a few minutes the GPU also dropped from 600Mhz to 200MHz. It was tested on RR3 and NOVA 3, and the game was found out rendering in full HD and upscaled to QHD. This is even slower than the LG G3 which features a Snapdragon 801 chip and which the same two games were running on QHD...
